This document summarizes the 1953 case Pharmaceutical Society of Great Britain v Boots. In the case, Boots Cash Chemists allowed customers to select items themselves from shelves and then bring them to a pharmacist at the register. The Pharmaceutical Society argued this violated a law requiring pharmacist supervision of prescribed drug sales. However, the court ruled that displaying items was merely an invitation to treat, and the sale only occurred when the pharmacist accepted payment from the customer at the register.
